Question

我尝试从设备相机上传图像并将其插入服务器上的文件夹中，如何修改下面的代码以将捕获的图像保存到数据库表中。

<?php
header('Access-Control-Allow-Origin: *');
require_once("db_connect.php");
$target_path = "image/";
if(isset($_FILES['file']))
{
$target_path = $target_path . basename( $_FILES['file']['name']);
 
if (move_uploaded_file($_FILES['file']['tmp_name'], $target_path)) 
{
    $image=basename( $_FILES["file"]["tmp_name"],".jpg"); // used to store the filename in a variable

    //storind the data in your database
  // $query= "INSERT INTO items VALUES ('{$image}')";
    //mysqli_query($con,$query);
echo "success";
} else 
{
echo $target_path;
    echo "There was an error uploading the file, please try again!";
}
}
?>

不是将图像保存到数据库，而是仅将图像的路径存储在数据库中可能更好。 我没有测试这段代码，但我认为你可以这样做：

// This is the folder name where the images are going to be uploaded.
$storeFolder = '/images';  

if (!empty($_FILES)) {
    $uploads_dir = __DIR__ . $storeFolder;

       $tmp_name = $_FILES["file"]["tmp_name"];
       $name = time() . $_FILES["file"]["tmp_name"];

       if (move_uploaded_file($tmp_name, "$uploads_dir/$name")) {
          //File is uploaded. Show some message if you want. 
       }else {
          //Handle error
       }  
}
